DNA is a double helix molecule that contains information that is used to make up a person’s body. DNA controls every aspect of a person’s body from their eye and hair color, height, and other features. DNA’s specific and unique characteristic can be crucial when solving a crime. DNA can be used to convict a suspect or exonerate an innocent person. When DNA is found it is even more important that is handle properly to ensure proper identification and accuracy of testing. The evolution of DNA technology is vital to the process of solving crimes, however the process by which DNA is found and handle can jeopardize its powerfulness.
The discovery of the structure of DNA opened the realm of DNA technology which changed the way crimes can be solved. In order to understand the importance of DNA in a crime, the structure of DNA needed to be revealed first. One of the most important discoveries in history was the discovery of the structure of DNA by Watson and Crick in 1953 (Liras, 2008). This remarkable molecule contained genetic information that can be highly useful in solving a crime. DNA is the basic unit of life. The molecule uses the arrangement of bases and forms into a double helix. This arrangement contains information and instruction for the development of the body. DNA defines each of our individual characteristics therefore making it very unique. The “arrangement of these bases in each DNA molecule is different for everyone except identical twins” (Wilson, Foreman & Asplen, 1999) and this is the key to the importance of DNA evidence. DNA is everywhere in the body and remains the same and that makes DNA a very important biological evidence. The individualistic characteristic is a key feature of DNA that assists in solving...

...ght crime, but funding sources can slow the process. If funding is not available for states to reduce their current offender backlogs, databases will remain unavailable to aid law enforcement with criminal investigations. . It is up to the criminal justice system is to realize the “full potential of DNA evidence as a crime fighting tool” (Wilson, Forman, & Asplen 1999), efforts must be made both to solve the database backlog of today and to promote DNA evidence use throughout all levels of law enforcement.
As criminals become cleverer, evidence like DNA becomes even more important. The discovery of DNA has truly helped in solving crimes and has proven to be vital evidence. However it can not be as powerful as it should if not handled or tested properly. DNA technology is still advancing and only time will time will reveal what will be available in the future.

Essay on DNA and Enzymes

- Have you ever asked yourself the question why my eyes are this color. Or any question as to why we look the way we do. All of our features come down to our genetics. Those genetics are family traits that are passed down through our bloodlines. It all comes down to what is considered the fundamental building blocks of life, our DNA. DeoxyriboNucleic Acid is the actual name for DNA. We have all heard of DNA for years, but what do you really know about it. What is DNA made of.

Essay about A Dna Database For All Citizens

- Since their first establishment in 1995 (Wallace, n.d.), the use of DNA databases has significantly increased. Today, DNA databases are rapidly expanding, with numerous countries using these databases for clinical research and to store criminal DNA (Roman-Santos, 2011). Their potential benefits and current assistance in solving crimes has caused huge controversy, especially surrounding the idea of a universal database. Although there are many benefits, including the identification and study of diseases, as well as improvements in crime detection and prevention, there are also various ethical concerns, such as the right to privacy and the potential for misuse if poorly regulated....   [tags: DNA, National DNA database, DNA profiling]

Use of DNA in Criminal Investigations Essay examples

- Before the 1980s, courts relied on testimony and eyewitness accounts as a main source of evidence. Notoriously unreliable, these techniques have since faded away to the stunning reliability of DNA forensics. In 1984, British geneticist Alec Jeffreys of the University of Leicester discovered an interesting new marker in the human genome. Most DNA information is the same in every human, but the junk code between genes is unique to every person. Junk DNA used for investigative purposes can be found in blood, saliva, perspiration, sexual fluid, skin tissue, bone marrow, dental pulp, and hair follicles (Butler, 2011)....   [tags: DNA Forensics]

DNA in the Forensic Science Community Essay

- This paper explores deoxyribonucleic acid (DNA) collection and its relationship to solving crimes. The collection of DNA is one of the most important steps in identifying a suspect in a crime. DNA evidence can either convict or exonerate an individual of a crime. Furthermore, the accuracy of forensic identification of evidence has the possibility of leaving biased effects on a juror (Carrell, Krauss, Liberman, Miethe, 2008). This paper examines Carrells et al’s research along with three other research articles to review how DNA is collected, the effects that is has on a juror and the pros and cons of DNA collection in the Forensic Science and Criminal Justice community.

The Power of DNA in the Courtroom Essay

- The Power of DNA in the Courtroom          In 1893, Francis Galton introduced a remarkable new way to identify people ("Fingerprinting" pg 1 par 3). His observation that each individual has a unique set of fingerprints revolutionized the world of forensics. Soon, all investigators had adapted the idea to use fingerprints as a form of identification. Unfortunately, over the course of the past century, criminals have adapted to this technique and seldom leave their incriminating marks at the crime scene....   [tags: Exploratory Essays Research Papers]
